unfortunately the AJAX upload of managed_file doesn't work with the latest 7.x-1.2-alpha1. I have a custom form with a managed_file field which naturally comes with an "Upload" button. Normally (and with any other theme) when I select a file and press "Upload" a throbber appears and the file is uploaded. Shortly after, the file name appears as a link within the form field.
However, when I select Tweme (or my Tweme subtheme) as my default theme, then the throbber does not terminate. It seems like the AJAX upload functionality is broken. When I install jQuery Update module, then file uploads work as desired. However, in that case Tweme complains and tells me to uninstall jQuery Update, as the theme doesn't need it any longer.
What would be the best way to work around this issue?
